This paper analyzes the interaction effect among multiple static var compensator-based damping controllers (SVC-DCs). The overall system is divided into the SVC-DCs and the external system for studies. Theoretical analysis indicates that the increase of the gain of a SVC-DC may cause an unstable control mode oscillation, and installation of another SVC-DC may cause destabilizing interactions between...
The parameter identification methods, which use the experimental data to identify the parameters of the excitation system model, are widely used in the power systems. Although the model parameters obtained by these methods can properly fit experimental data, the identification results of some parameters may be unstable. To address this problem, this paper proposes a conception called sub-frequency...
